Isimiso se-Proton exchange membrane, imakethe kanye nokukhiqizwa kwe-proton kwethu komkhiqizo we-exchange membrane isingeniso

In i-membrane yokushintshana kweprotoniIseli likaphethiloli, i-oxidation ye-catalytic yama-proton iyi-cathode ngaphakathi kwe-membrane, ngesikhathi esifanayo, i-anode yama-electron ukuze ithuthele ku-cathode ngesekethe yangaphandle, ikhwalithi ihlanganiswe nokunciphisa kwe-oxygen kagesi kanye ne-cathodic ebusweni bamanzi akhiqizwayo, amandla akhiqizwa ugesi ngokusebenzisa ukuqhutshwa kwesekethe yangaphandle. Ku-membrane ejwayelekile ye-proton exchange membrane fuel cell membrane electrode kanye nokusebenza kahle kuyisici esibalulekile, futhi ukuqhutshwa okuphezulu kwe-proton kuyisici esibalulekile sezinto zokwakha i-membrane exchange proton. I-membrane exchange proton ivame ukwakhiwa ngesakhiwo esihle sokuhlukaniswa kwe-hydrophobic kanye ne-hydrophilic, isakhiwo se-hydrophobic ukugwema ukumuncwa kwamanzi ngokweqile, okwenza ukuvuvukala kwe-membrane kube kuphansi, kugcinwe ukuzinza kwe-membrane; Amaqembu e-hydrophilic e-sulfate aqhuba isiteshi anikeza okwanele, kungaba ama-proton kusuka ku-anode kuya ku-cathode, ingxube kaphethiloli yegesi ngesikhathi esifanayo.

Amaseli kaphethiloli e-proton exchange membrane okuqala anezinkinga zezindleko eziphakeme kanye nokuphila okufushane ngenxa yokusetshenziswa kwama-membrane e-polystyrene-styrene copolymer aqukethe i-sulfonated. Ngawo-1970, i-Nafion membrane yathatha indawo ye-polystyrogen-divinylbenzene copolymer membrane njenge-membrane ejwayelekile yamaseli kaphethiloli e-proton exchange membrane.

I-membrane ye-all-gas sulfonic acid idinga ukusebenza ngaphansi kuka-100°C, futhi uma izinga lokushisa liphakeme kuno-100°C, i-membrane iyaphela ngokushesha futhi izindawo ze-ionic esakhiweni se-membrane ziyawa, okuholela ekwehleni okukhulu kokuqhuba. Njengamanje, amaseli amaningi kaphethiloli asebenza emazingeni okushisa angaphansi kuka-100°C, kodwa lokhu akulona iqiniso. Ngakho-ke,ulwelwesi lokushintshana kweprotoniezingakwazi ukuzivumelanisa namazinga okushisa aphezulu zidinga ukuthuthukiswa kabanzi. Isikali sokukhiqiza sinomthelela omkhulu ezindleleni zokukhiqiza ze-proton exchange membrane. Izindleko ze-proton exchange membrane zakhiwe kakhulu izingxenye ezintathu: (1) izindleko zezinto ze-ionomer; (2) Izindleko zezinto ze-polytetroxene enwetshiwe kanye (3) izindleko zokukhiqiza amafilimu. Izindleko zezinto kanye nokhuni lokukhiqiza kokubili kuthinteka yisilinganiso sokukhiqiza. Lapho isikali sokukhiqiza sikhuphuka kusuka kumasethi ayi-1000 ngonyaka kuya kumasethi ayi-10000 ngonyaka, izindleko zokukhiqiza ze-proton exchange kanye ne-film exchange zingancishiswa ngo-77% kanti izindleko eziphelele zingancishiswa ngo-70%.

I-VET Technology Co., Ltd ingumnyango wezamandla we-VET Group, okuyinkampani kazwelonke yobuchwepheshe obuphezulu egxile ocwaningweni nasekuthuthukisweni, ekukhiqizweni, ekuthengisweni nasekusethweni kwezingxenye zamandla zezimoto nezintsha, ikakhulukazi esebenzela uchungechunge lwezimoto, amaphampu e-vacuum, ibhethri likaphethiloli kanye ne-flow, nezinye izinto ezintsha ezithuthukisiwe.

Eminyakeni edlule, siqoqe iqembu lamakhono embonini anolwazi futhi asungula izinto ezintsha kanye namaqembu e-R & D, futhi sinolwazi oluningi olusebenzayo ekuklanyweni komkhiqizo kanye nezicelo zobunjiniyela. Siye sazuza ngokuqhubekayo impumelelo entsha ekusetshenzisweni kwemishini yokukhiqiza inqubo yokukhiqiza kanye nomklamo womugqa wokukhiqiza ozenzakalelayo kancane, okwenza inkampani yethu ikwazi ukugcina ukuncintisana okuqinile embonini efanayo.

Ngamakhono e-R & D kusukela ezintweni ezibalulekile kuya emikhiqizweni yokugcina yohlelo lokusebenza, ubuchwepheshe obuyisisekelo nobubalulekile bamalungelo obunikazi obuzimele bufinyelele izinto eziningi ezintsha zesayensi nobuchwepheshe. Ngenxa yekhwalithi yomkhiqizo ezinzile, uhlelo lokuklama olungabizi kakhulu kanye nensizakalo esezingeni eliphezulu ngemuva kokuthengisa, sithole ukuqashelwa nokwethenjwa ngamakhasimende ethu.

Ama-membrane e-Nafion PFSA akhiqizwe yi-VET Energy angama-membrane angaqiniswanga asekelwe kuma-polymer e-Nafion PFSA, ama-copolymer e-sulfonic acid/polytetrafluoroethylene acwebezelayo ngesimo se-asidi (H+). Ama-membrane e-Nafion PFSA asetshenziswa kabanzi ku-i-membrane yokushintshana kweprotoniAmaseli kaphethiloli (PEM) kanye nama-electrolyser amanzi. Ezinhlobonhlobo zamaseli e-electrochemical, ama-membrane asebenza njengabahlukanisi kanye nama-electrolyte aqinile futhi ayadingeka ukuze adlulise ama-cation ngokukhetha ezindaweni zokuhlangana kwamaseli. I-polymer imelana namakhemikhali futhi ihlala isikhathi eside.
